摘要：

We developed a narrow line width terahertz and mid-infrared source based on difference frequency generation(DFG) in GaSe crystal. The source could be easily continuous-tuned in a terahertz region of 68.1-1386 mu m (0.22-4.4 THz) and a mid-infrared region of 16.1-26.5 mu m without altering any component. The maximal peak power of terahertz waves is 9.1 W at 143 mu m (2.1 THz), which corresponds to a power conversion efficiency of 2.8x10(-5). Using a FTIR spectrometer, we verified the wavelength and the line width of the source.
